They pay poor attention to users who have no programming abilities but need to customize software applications. At some point, such needs force end-users to act as designers in various aspects of software authoring and development. Every day, more new computing-related professionals attempt to create and modify existing applications in order to customize web-based artifacts that will help them carry out their daily tasks. In general they are domain experts rather than skilled software designers, and new authoring mechanisms are needed in order that they can accomplish their tasks properly. The work we present is an effort to supply end-users with easy mechanisms for authoring web-based applications. To complement this effort, we present a user study showing that it is possible to carry out a trade-off between expressiveness and ease of use in order to provide end-users with authoring facilities.The work reported in this paper is being partially supported by the Spanish Ministry of Science and Technology (MCyT), projects TIN2005-06885 and TSI2005-08225-C07-06
